If at all..meaning I wouldn't, ever...maybe Tomoko for a girl. Although I really like the name Ranma.
Anyways. what's up with this unreasonable obsession over japanese and japanese culture. Sure it is awesome, but for some reason it seems to be a young teenager obsession usually because of an anime show like Naruto, Inuyasha or Yu-Gi-Oh. I mean if you are really interested in it then learn aboot it, there are ways to not be too nerdy aboot it.
